Smart contracts
EVM contract design and implementation for payments, escrow, vaults, access control, and business-specific on-chain rules.
Build with WARMKEY
Smart Contract Development
When a payment gateway is not the whole product, we build the on-chain logic, DApp interface, and supporting systems around your business rules.
One team for contracts, DApps, and the glue in between
We do not sell a menu of disconnected IT tickets. The same team that runs WARMKEY payment infrastructure can extend into the product you actually need to ship.
DApps
User-facing Web3 applications: wallet connect, on-chain actions, merchant consoles, and product flows that sit on top of the contracts.
Supporting systems
APIs, admin tools, indexing, and integration with your existing backend so the on-chain part is usable in daily operations.
Typical work we take on
Most requests start from a payment or fund-control problem, then expand into the product around it. That is where WARMKEY is strongest: on-chain money movement plus the software that operates it.

Payment, settlement, and merchant-controlled signing logic
Custom escrow, vault, or release conditions
DApp checkout, dashboard, or operator console
Backend services that watch chain events and update your product
Integration with an existing website, app, or finance workflow
How we work
01
Scope the outcome
What the user, operator, and ledger must do when the contract or DApp is live.
02
Design the surface
Contract boundaries, permissions, and the smallest product that is safe to ship.
03
Implement
Contracts, interfaces, and backend pieces built against the agreed flow.
04
Verify & hand over
Test coverage, deployment notes, and an operating path your team can run.
FAQ
Do you only write Solidity contracts?
Contracts are the core, but most projects also need a DApp, admin tools, or backend integration. We treat those as one build, not separate vendors.
Can this connect to the WARMKEY payment gateway?
Yes. Many builds sit next to WARMKEY deposits and payouts: custom release logic, operator consoles, or product-specific credit rules.
What if we already have a product and only need the on-chain part?
That is fine. We can implement the contract and the minimum interface your current system needs to call it.
Is this a generic software shop offering?
No. We take Web3 payment, fund-control, and merchant-operation problems first. Broader IT work is accepted when it belongs to that same product.
Bring the contract and the product to the same table.
Share the business rule you need on-chain. We will tell you whether it should be a contract, a DApp, a WARMKEY payment flow, or a mix.
